Typical repair cost, by problem

Rear subframe corrosion at suspension mounting points in salt-belt states is covered by a confirmed recall, but owners report parts-availability issues preventing the repair — a confirmed new instance of both a frame/subframe-rust pattern and its parts-unavailable pattern. Separately, a taillight moisture-intrusion recall required a later follow-up campaign because the original remedy didn't resolve the defect.
